In" order to' position the. tubular member relatively to the upstandihgprojections: 21; 22,.23" suitable stops 25, 26-ar1e provided at oppositeends of the row of. upstandingjprojections' 21122, 23 and fnrther'stopssuch as 27-,

2'8*are' provided at on'near theiends" on one side of theupstandingprojeetions; A central stop 29i's also provided in alignmentwith the stops 27, 28.

When the tubular member has been fitted on the upstanding projections21, 22, 23 and the steps 25, 26, the cells may be formed manually bypressing the top of the inset inwardly along the scoring lines Itwithout the risk of crushing down the partition between the cells 5, 6.

If desired the side walls of the upstanding projections 21, 22, 23 maybe recessed on their opposite faces, whilst the inner faces of the wallsof the stops 25, 26 may be similarly recessed.

The cells such as 5, 6, however, are preferably formed by means of aplunger device having plungers 30 of which the number preferablycorresponds with the number of cells to be formed. The plungers 30 havethe general shape of the cells to be formed. Each plunger has a reducedend 31 so as to facilitate its entrance into the slit 41, the reducedend 31 gradually merging, as

. 3 shown in Fig. 11, into the shape corresponding with the shape of thecells 5, 6.

The plungers 30 are mounted on a support 32 which is hinged at 33 tomembers 34 mounted on the base 20. The support 32 is preferably springactuated, as indicated at 35, the spring action normally tending to movethe plungers away from the cells.

The action of the springs 35 is limited by chains 36.

3. An appliance according to claim 1, wherein each plunger is of generalrectangular shape having an end projecting portion extending across theend face of the plunger and having inclined faces which connect theprojecting portion to the rectangular portion of the plunger.

4. An appliance for use in forming compartments in a cardboard unit oftubular outline wherein such unit is provided with pairs of spaced scorelines extending transversely thereof at spaced intervals to formcompartments intermediate such score lines in the top wall of the unit,a score line and a slit in the bottom wall opposite each pair of scorelines in the top wall, a slit at each end of each of said last namedscore lines arranged at right angles thereto and extending to the slitto form a flap at both sides of the compartments intermediate the pairsof score lines and a score line at one end of the outermost compartmentsalongthe bottom and a slit at each end of the last named score linesarranged at right angles thereto and merging therewith to form a flap atthe outer side of each of the outermost compartments, comprising a base,a plurality of spaced upstanding projections, the projections being ofsuch a thickness to permit the projections to enter the flap openingsand being of suflicient height and width to engage and support the topwall of the tubular unit substantially completely thereacross, stops onsaid base at opposite ends of the row of said upstanding projections,further stops at the ends on one side of said upstanding projections, acentral stop in alignment with said last mentioned stops, aspring-actuated support hinged to said base for movement toward and awayfrom said projections, a plurality of spaced plungers secured to saidsupport, each of said plungers having a reduced end extending centrallyacross the same and then merging gradually into a shape correspondingwith cells to be formed, and chains connected to the support and baselimiting the spring action on the support.
